Space saver, short guarantee
Photovoltaic panels from the GCL-M10/72H series utilize large-format M10 cells, which represent the market standard in the field of high-efficiency industrial installations. A key innovation is the use of gallium doping, which effectively protects the modules against LID degradation and guarantees long-term stability of electrical parameters. The design based on half-cut cell technology and a multi-busbar (MBB) system allows for a significant reduction in resistive losses and better performance under partial shading conditions. This series addresses the cost-efficiency of large projects by offering an optimized power-to-area ratio, which effectively reduces expenditure on mounting structures and cabling. Designed primarily for utility-scale solar farms and commercial investments, it stands out from the competition with excellent resistance to potential-induced degradation (PID) and high mechanical strength. By choosing these modules, investors ensure high yields even in difficult weather conditions, as confirmed by their low temperature coefficient of power. This is a professional solution for experts focused on maximizing the LCOE ratio and long-term energy security of the system.

Using gallium instead of boron as the dopant effectively eliminates light-induced degradation (LID), which in conventional P-type PERC cells can consume 1-2% of rated power during the first months of operation. This represents a tangible advantage over legacy PERC modules that lack this improvement.
The half-cut cell architecture (144 cells) combined with a multi-busbar (MBB) interconnection scheme reduces resistive losses and improves performance under partial shading conditions - a meaningful benefit for commercial and industrial installations where uniform irradiance cannot always be guaranteed.
GCL System Integration appears on the Bloomberg NEF Tier-1 module manufacturer list, meaning it has secured financing for at least six projects exceeding 10 MW through independent commercial banks within the preceding 24 months. This status is critical when pursuing project finance for utility-scale PV plants.
Peak module efficiency reaches 21.87%, placing the series directly alongside comparable Tier-1 products such as the JA Solar DeepBlue 3.0 Pro and the LONGi Hi-MO 5m G2, both rated at 21.9%. A difference of less than 0.05 percentage points is negligible in practice for utility-scale projects.
The high per-module power rating reduces the number of panels required per installed MW, directly lowering Balance of System (BoS) costs - cabling, racking structures, and installation labor - a key input when calculating LCOE for large-scale projects.
The GCL-M10/72H series has discontinued status; availability of new modules is limited to distributor warehouse stock. In the event of warranty replacements or system expansion years down the line, sourcing identical modules for string matching will be difficult or impossible.
By 2025, TOPCon surpassed PERC as the dominant market technology, accounting for approximately 49-66% of global manufacturing capacity, and offering module efficiencies of 22-24% with a lower degradation rate. Selecting a PERC module over an N-type TOPCon product for new solar farm projects now requires explicit cost justification.
The series is monofacial (is_bifacial: false), while the utility-scale segment increasingly specifies bifacial modules to maximize albedo-reflected energy gain (typical bifacial gain: 5-15% depending on ground surface). The bifacial TOPCon market for ground-mounted arrays was valued at USD 23.45 billion in 2024 and continues to grow rapidly.
- Efficiency of 21.7% matches the PERC 550-600W median
- At 216.8 W/m² power density, this panel generates 3.9 W/m² more per unit area than PERC 550-600W median (212.9 W/m²)
- At -0.35%/°C, hot weather performance is typical for PERC 550-600W panels
- Weight of 27.7 kg (3.1 kg below PERC 550-600W median of 30.8 kg) allows easier transport and roof mounting
- #7606 for efficiency, #10489 for temperature performance out of 14129 panels
